MicroPure filtration system cuts sterile air filter maintenance costs

MicroPure Filtration’s segmented sterile air and gas filtration system is designed to capture sub-micron contaminants while significantly reducing maintenance and operating costs in food, beverage, and pharmaceutical processing facilities.

The patented design uses a self-sealing polytetrafluoroethylene membrane with 0.1- or 0.2-micron retention efficiency, supported by perforated 304 stainless steel segments housed within a stainless-steel enclosure. Unlike conventional pleated cartridges, the system operates without disposable filter bags or elements.

According to MicroPure Filtration, the filters can be steam sterilized in place up to 150 times with no loss of filtering effectiveness, as validated by third-party laboratory testing. This performance allows processors to avoid frequent cartridge replacement and the degradation commonly associated with repeated sterilization cycles.

Air or gas enters through openings on the exterior of each segmented disc, passes through the membrane, and exits through the center of the cartridge free of contaminants. The design supports bi-directional flow and higher flow rates while maintaining submicron bacterial retention.

The modular construction allows operators to scale filter capacity by adding support discs and membrane media without purchasing a new housing. When replacement is required, only the membrane media is changed, reducing disposal volume and replacement costs.

MicroPure sterile air and gas filters are intended for bulk or point-of-use applications such as bottling and canning lines, packaging operations, wort aeration, and other processes where contamination control is critical.

All MicroPure products are manufactured in Cleveland, Ohio, and the company offers custom housing designs to meet specific flow rates and process requirements.
